r r 1 Claim. 1 r

This invention relates to the combination of sink and a'container washing apparatus; Specifically, it relates to a support for anapparatus of this type employing three adjacent revolving brushes, thetwo outside brushes being used to cleanse the interior of the containers, such as drinking glasses, and the center brush is used to simultaneously'cleanse the exterior of the glasses which are disposed around the outside brushes.

The present invention contemplates using three substantially horizontal brushes, a motor and a driving connection between the brushes and the motor. All of the parts are disposed in a compact unit which can be easily removed or installed along one sidewall of a sink. It is designed compactly enough to fit in and be attached to the ordinary sink and allow room for its use so as to make a practical glass washing machine out of the ordinary sink. It is not necessary to have any space behind the sink such as a table or support, in order to hold the apparatus in proper position. In other words, the present unit is so constructed that it can be used by many concerns that already have their sinks for dishwashing purpose without making any alterations in the existing equipment or layout.

It is therefore an object of this invention to provide a support for a glas washing apparatus, installed in a unit which can be easily and efiectively used in combination with a sink for 'washing containers such as glasses, bottles, and the like. The simplicity of the present apparatus makes it possible for any small restaurant to obtain a glas washing machine at a very low price and install it with existing equipment. This type of machine will not only give a perfectly washed glass, but will save breakage over the common plan of piling glasses in a sink to soak.

Some of the objects of the invention having- Figure 4 is a sectional detail view through one of the brushes and through a glas which has been placed thereon, said view being taken along the line 4-4 in Figure 1;

ing a slightly modified form of support for theapparatus; v

Figure 6 is an isometric view of the bracket which is used for supporting the lower portion 7 of the glass washing machine in Figure 5.

Referring more specifically to the drawings, the numeral 9 denotes suitable legs or supports which have attached to the upper end thereof, a container or sink w. This sink has compartments II and 12 therein, the compartment ll being adapted to contain soapy water H and the compartment 12 being adapted to contain clear cool water it. or sink has an apron l6 integral therewith, and extending upwardly a substantial distance above the other walls. A frame I! has bolts l8 penetrating the same which secure a bracket l9 to the frame l'l. Bracket I9 has an upper hooked portion which fits over the upper edge of back wall It. Bracket l9 ha slot 2| penetrated by bolts l8 for vertical adjustment of the bracket I9.

Figure 5 is a View similar to Figure 1, but show- 65 Usually the material from which the sink [0 is constructed is of very thin gauge and therefore, an additional supporting means is advisable. vided which extends from the bottom of the frame I! to the bottom of the sink Hi. This support is designated by the reference character 25, and has suitable slots 26 in the upper end thereof, said slots being penetrated by stud bolts 21 which are also threadably secured in the frame ll. The purpose of the slots 26 is to permit a substantial amount of vertical adjustment so that the bottom of the support will fit firmly against the bottom of the sink. It will be noted that the lower portion of the support 25 has a foot portion 29 integral therewith which forms a base for contact With the bottom of the sink Ill.

The lower portion of the frame II has three hollow shafts rotatably mounted therein, each of these shafts having a hollow bore 36 therein and-each of said bores being tapered as at 31 so as to accommodate a tapered end 38 on a brush shaft 39 (Figures 2, 3, and 4). The three shafts 39 are identical and have brushes 40, 4|, and 42 mounted thereon. When these brushes are installed in the manner shown in Figures 1 and 2, the peripheries thereof contact each other, so that when a glass 43 is placed on either of the brushes 40 and 42 in the manner shown in Figures 1 and 4, the interior as well as the exterior of the glass will be washed. The purpose of providing the hollow cavities or bores 36 is to permit easy removal of the brush shafts 39. When it is desired to remove the brushes, it is only necessary One of the sidewalls of the container Therefore, an additional support is pro- 7 to take a rod and insert it in the open end of the bores 36, and apply the necessary pressure to remove the tapered end 38 from tapered bore 31.

By referring to Figure 3, it will be seen that two of the hollow shafts 35 have gears 46 and 41 mounted on one end thereof. These gears 46 and 4'! drive brushes 40 and 4|, respectively, which are employed for washing the glasses 43. The third hollow shaft is associated with outside brush 42, butrdoes not have a gear thereon;

The two outer shafts 35, upon which brushes 48 and 42 are mounted have pulleys D and 5t respectively, mounted thereon, said pulleys having a belt 52 engaging the peripheries thereof. This belt extends upwardly and is mounted upon a motor pulley 54, said pulley being fixedly'secured on motor shaft 55 of. motor 56. Motor 56 is mounted upon a base 5! which base has a downwardly extending flange 58 integral there- 'with which flange overlaps the upper portion of frame I1. This downstanding portion has slots 59 therein which are penetrated by stud bolts [ill and these stud bolts are threadably secured to the upper portion of the frame H. Byloosening these bolts and raising or lowering the motor base 51, the tension in the belt 52 can thereby be/regulated. The bolts 60 are assisted by suitable set screws 6| which are threadably secured in the upper portion. of the frame IT. The upper ends of screws 6| normally engage the base 51. When the stud bolts 60 are loosened, the set screws El are regulated to adjust the height of the motor 55. Suitable lock nuts 62 are employed upon the set screws Bl tov lock them in adjusted position.

The base 51 also has a. groove 63 therein which accommodates a suitable shield 64. This shield serves to catch spray and the like which is thrown, from the, brushes 49, 4|, and 42 during a, glass washing. operation; V

It is seen that by observing Figure 2, practically" all of-the moving parts, with the exception of the brushes, are disposed adjacent the apron I6 of the sink and therefore in a, position where a person will be unlikely to contact the. same or become injured. By providing this arrangement, the whole unit occupies a minimum amount of space in a sink, which of, course, will leave more room for washables such as dishes: or the like. It is; therefore, seen. that I have provided a ma-, chine that has a. flexibility of usage, as well as. a. very eflicient, economical and, simple apparatus.

Figures 5: and 6 show a slightly modified form of mounting for the glass washing apparatus. The chief difierence in the form shown in Figures 5 and 6 and that of the previous form is the elimination of the support 25 wln'ch extends to the bottom of the sink, and the substitution therefor of a U-shaped support 61. This U-shaped support 61 has a hole 68 in the central portion thereof which is penetrated by a bolt 69, said bolt also penetrating a washer l0 and being.: threadably secured in the' lower portion of frame H. The ends of the U-shaped' brackets 61 have horizontally extending flanges II which rest upon the rims 12 and 13 of the sink. This form of support has the advantage of a quick installation on an existing sink although it does not permit vertical adjustment of the frame [1.

Process. of washing 'Iakev one glass in each hand and dip in soapy Water. Then push glasses right over the two outside brushes, holding loosely, and glasses will revolve with brushes, which allow center brush to clean outside while brushes in glass clean inside. This is done very quickly allowing speed of operation. Glasses are then usually dipped in clear cool water in second compartment, to flush ofi soapy water. v

In the drawings and specification, there has been. set forth a preferred embodiment. of theinvention and although specific terms, are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in. the claim.

I claim: Means for supporting aeglass. washing machine in a sink, wherein the sink has a rear Wall extending upwardly a substantial distance above the end and front walls, a bracket secured to.

the machine. and projecting rearwardly against.

the rear wall of the sink and then projecting upwardly and then rearwardly over the top of the rear wall of the sink and having a. downturned portion fitting against the rear surface of the rear wall of the sink. for supporting the glass washing machine a substantial distance above the bottom of the sink, and. means secured to the lower portion of the glass. washing machine and resting by gravity on a portion. of the sink for also supporting the machine with relation tothe sink.
